What WIDI Recognition System is
WIDI Recognition System is desktop software for turning recorded or live audio into MIDI and supporting music transcription and analysis. It accepts Wave, MP3, CD Audio, WMA, and AIFF files, with polyphonic transcription, chord detection, batch processing, and MIDI export. Offline recognition offers several adjustable algorithms, including drum detection. Realtime recognition converts playing into MIDI while an instrument is being played, with adjustable settings and a sliding spectrogram. Composition Analysis examines detuning and musical tonality in audio or MIDI files. Professional edition includes TrueTone Editor, a piano-roll view that places spectral peaks beside MIDI notes and synchronizes score display with playback; Standard uses the same transcription algorithms without that editor. WIDI also plays audio and MIDI together, records audio, and records MIDI from a keyboard. It runs on Windows and macOS. A 20-day trial saves only the first 10 seconds of transcribed MIDI.
